OSTV720A151 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTV720A151 is a 20-position terminal block header manufactured by On Shore Technology Inc., featuring female sockets with 0.295" (7.50mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The part operates at 10 A (UL) and 300 V (UL) with UL94 V-0 flammability rating and ROHS3 compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTV720A151 is determined by the following critical parameters that must remain consistent or compatible:

• Number of Positions: 20 positions (fixed requirement)
• Header Orientation: 90° right-angle configuration (fixed requirement)
• Mounting Type: Through-hole solder termination (fixed requirement)
• Type: Header with female sockets (fixed requirement)
• Current Rating: 10 A (UL) minimum
• Voltage Rating: 300 V (UL) minimum
• Flammability Rating: UL94 V-0 (fixed requirement)
• RoHS Compliance: ROHS3 Compliant (fixed requirement)

The substitute part V72071510000G from Amphenol Anytek meets these core functional requirements. The primary difference is the pitch specification: the substitute operates at 0.197" (5.00mm) pitch versus the original 7.50mm pitch. This represents a mechanical redesign consideration for PCB layout and connector interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

The V72071510000G substitute part maintains electrical and safety compliance with the original OSTV720A151 specification. Both components are ROHS3 compliant, carry UL94 V-0 flammability certification, and support identical current and voltage ratings. The substitute part holds active product status, ensuring continued availability and supply chain support.

The primary design consideration is the pitch difference: 7.50mm (original) versus 5.00mm (substitute). This dimensional change requires PCB layout modification and connector interface redesign. The substitute provides an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), which may offer improved thermal performance in certain applications.

Frequently Asked Questions (FAQ)

Q: Can V72071510000G be used as a direct drop-in replacement for OSTV720A151?

A: No. While both components share identical electrical ratings, current capacity, voltage rating, and safety certifications, the pitch difference (7.50mm versus 5.00mm) requires PCB layout modification. Direct physical substitution without redesign is not possible.

Q: What are the key compatibility factors between these parts?

A: Compatibility is determined by: 20-position count, 90° right-angle orientation, through-hole mounting, 10 A current rating, 300 V voltage rating, UL94 V-0 flammability, and ROHS3 compliance. All these parameters match between the original and substitute.

Q: Does the substitute part offer any performance advantages?

A: The V72071510000G provides an extended operating temperature range (-40°C to 115°C) compared to the original (-30°C to 105°C). The substitute also maintains active product status, ensuring long-term availability.

Q: Are there packaging differences between these parts?

A: The original OSTV720A151 packaging is listed as unspecified. The substitute V72071510000G is supplied in bulk packaging.

Q: What certifications and compliance standards apply to both parts?

A: Both components are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8536.69.4040.
